The RSST ETF combines U.S. large-cap equity exposure with a managed futures strategy, aiming for capital-efficient 'return stacking' but has shown high volatility and recent drawdowns. RSST's managed futures strategy uses a machine learning approach similar to DBMF, which has faced significant losses due to sudden market changes. I recommend investors watch RSST closely and avoid investing until the fund can demonstrate consistent alpha generation from its managed futures overlay.
